I think there comes a moment in most of our lives when we know something, but are loathe to do anything about it. Small things like, "I know I need to take out the garbage.... but it can wait until tomorrow." Or change the toilet paper roll, as the new roll sits next to the holder. Or return a phone call. Maybe you don't have these reluctances as I do. If not, please tell me how you do it! Perhaps we're just wired differently.
But there are bigger things, too -- taxes, resolving anger issues, communicating important dates. And, while these things have sometimes greater consequences than a toilet paper roll (or not), am I (trying not to gather all the world into my issues) more loathe to do them?
Knowing and doing are two different things. I know, "Thank you, Pastor Obvious." Sometimes, for the sake of my own head, it needs to be stated simply and concretely. I'll move on from there.
